The company is incorporated in San Francisco but we're working from Paris/remotely for now. \n\n# What's so special about engineering at Multis?\n\nMost people would call Multis "just an interface" but you'd probably call it a server-less, backend-less, password-less, real-time fullstack ClojureScript static decentralized web application. It's not about ticking boxes though — we chose these technologies and architecture to cater for our very specific domain: the blockchain. As for our engineering principles, we only have one: simplicity.\n\n# Mission\n\nWe're looking for a fullstack engineer to work hand-in-hand with the CTO and the engineering and product teams to build and maintain our next-gen business banking stack and features — leveraging blockchains and their protocols as well as server-less infrastructure and functional programming. As a core member, we also expect you to have major impact on shaping our culture and brand, and help us attract top talents!\n\n# Benefits\n\n* Challenging work experience building next-gen banking with a frontier tech\n\n* Fast-learning environment, entrepreneurial and strong team spirit\n\n* Unique access to the Y Combinator and eFounders network\n\n* Competitive salary & equity\n\n* Remote-friendly company with offices in Paris downtown (75002)\n\n* Off-sites abroad (next one will be in the Canary Islands)\n\n* Possibility to get all or part of your salary in crypto 🤑 \n\n# Responsibilities\n * Lead features development — from specs to tested production code — along with the Product team\n\n* Contribute to Multis technical thought leadership through articles on our engineering blog \n\n* Maintain product and handle company-wide support with the core team\n\n* Help build a world-class engineering team \n\n# Requirements\n* 2+ years of experience as a fullstack engineer\n\n* Acquainted with ClojureScript (or strong willingness to learn — our coding test is in ClojureScript)\n\n* Experience with complex single page applications\n\n* Ability to lead projects and execute with pragmatism and velocity\n\n* Cultivate humility and curiosity about all things programming and tech\n\n* Know how to relax 🏝️ \n\n\n\n**Nice to have:**\n\n* Startup experience — ideally B2B or fintech\n\n* Passionate about all things blockchain and crypto\n\n* Experience leading a team (or strong appetite to do so)\n\n* Previous remote experience\n\n* Hawaïan outfit and prior one-pot experience 🍲 \n\nBe sure to mention the words **QUANTUM TOILET BIRD** when applying to show you read the job post completely.

***In compliance with federal law, all persons hired will be required to verify identity and eligibility to work in the United States and to complete the required employment eligibility verification form upon hire.***\n\n\n**Job type:** Full-time \n**Role:** Full-Stack Developer \n**Experience level:** Mid-Level, Senior\n**Industry:** Cryptocurrency, Cybersecurity, Network Security, Blockchain \n**Company size:** 11-50 people\n**Location:** San Diego, CA, San Juan, Puerto Rico, Tokyo, Japan or **Remote**\n\n\n**Join the Swarm**\n\nAt Swarm Technologies, Inc, we're developing innovative solutions to age-old information security problems - and we need your help.\n\nAt its core, PolySwarm is market design enabled by Ethereum smart contracts. We are programming a market that will produce crowdsourced threat intelligence (malware detection today, more tomorrow).\n\n** Blockchain experience not required! **\n\nWe're operating in a very new industry and we're prepared to bring candidates up to speed! Few sectors are hot as blockchain right now - talk about professional growth\n\nNo one has done this before. We'll get things wrong - and that's okay! With your help, we'll get fewer things wrong, identify mistakes earlier, and improve processes to prevent future missteps.\n\nYou're in on the ground floor - you'll have a say in what we do and how we do it. By joining Swarm Technologies, you'll be joining a dynamic team on the bleeding edge of information (computer) security and blockchain - answering questions few have thought to ask.\n\n**If you're interested in**\n- technical challenges that cannot be solved via iteration\n- blockchain (Ethereum smart contracts in particular)\n- information security\n- malware reverse engineering automation\n- market design (a la Who Gets What and Why by Alvin Roth)\n- software development\n- unknown unknowns\n\n**then we're interested in you!**\n\n**The Ideal Candidate Is:**\n- independently motivated & self-directing\n- introspective: able to identify weak spots / problem areas our existing processes or code and suggest / implement solutions\n- takes an interest in information security topics - huge props for capture the flag (CTF) participation!\n- enjoys developing software\n\n**At Swarm Technologies, you'll tackle both big-picture and tactical problems, the following are a few examples.**\n\n**Example Big-Picture Problems**\n\nThe Ethereum block time leaves a lot to be desired for a marketplace that intends to supplant millions of malware scans a day.\n\nHow do we best reconcile millions of scans daily with a 15 second block time and today's block size limits?\n\nIn sum: PolySwarm must scale and must support scanning artifacts (files) that may contain confidential information. How do we best reconcile these needs with a default-public, Proof-of-Work Ethereum ecosystem?\n\n**Example Tactical Problem**\n\nPolySwarm is a twist on a prediction market - where security experts attempt to "predict" whether a file / URL or network traffic is malicious or benign. Alongside their prediction ("assertion"), experts "stake" a configurable amount of Nectar (NCT), PolySwarm's crypto token.\n\nSuppose Expert A is lazy and Expert B is a hardworking, upstanding security expert. It would be bad if Expert A was able to simply duplicate the assertions coming from Expert B, exploiting Expert B's hard work for profit. If assertions are placed directly on the public Ethereum blockchain, Expert A can do exactly that.\n\nHow can we design a system that keeps the assertion secret (so Expert B is out of luck) until some configured time, after which assertions are revealed and payouts distributed appropriately?\n\n**The Ideal Candidate possesses demonstrable experience in some or all of these technologies.**\n\nPolySwarm employs the following tools & languages:\nPython\nDocker (+ Swarm, Services, Stack)\nKubernetes (+ Helm)\nTerraform\nAnsible\nSolidity\nReact\nJavaScript\nRust\n\nRefer to our GitHub for examples of our usage: https://github.com/polyswarm\n\n**We Offer**\n- Competitive salaries\n- Excellent health, dental, vision coverage\n- Paid vacation days\n- Travel (if you like). We have offices in San Diego, Puerto Rico and Tokyo and we often find ourselves travelling elsewhere. If travel interests you, we can scratch that itch.\n- Flexible work hours - outside of scheduled meetings, we don't care when you work, we care about your output.\n- Powerful servers, laptops, desktops - whatever you need to be most productive! \n\nBe sure to mention the words **DELAY BECAUSE VAGUE** when applying to show you read the job post completely.
